Measurements of X- and γ-ray emission probabilities in the β− decay of 233Pa

X- and γ‐ray emission probabilities from the β− decay of 233Pa were measured with planar (LEPS) and coaxial Ge detectors. A 233Pa source was produced after radiochemical separation from a 237Np sample in which the parent (237Np) and daughter (233Pa) nuclides were in secular equilibrium. The results are compared with previous measurements and data evaluations.
